Quick start

1. Create an account, start the free trial or buy a plan, and create a key in Dashboard → Developer API.
2. Send your key in the Authorization header.

curl -X POST https://ajontectool.com/v1/tools/pdf-compress \
  -H "Authorization: Bearer ajt_YOUR_KEY" \
  -F "files=@document.pdf" \
  -F "level=recommended"

Response:

{
  "ok": true,
  "tool": "pdf-compress",
  "message": "Reduced from 2.10 MB to 0.64 MB (70% smaller).",
  "files": [{ "name": "document-compressed.pdf", "size": 671088,
              "url": "https://ajontectool.com/v1/files/3f2a…/0" }],
  "expires_in_minutes": 60,
  "credits_used": 1
}

Download the result with the same key: curl -H "Authorization: Bearer ajt_YOUR_KEY" -o out.pdf FILE_URL. Files are deleted after 60 minutes.

const form = new FormData();
form.append('files', new Blob([fs.readFileSync('photo.jpg')]), 'photo.jpg');
form.append('quality', '70');
const r = await fetch('https://ajontectool.com/v1/tools/image-compress', {
  method: 'POST', headers: { Authorization: 'Bearer ' + process.env.AJT_KEY }, body: form });
const data = await r.json();

r = requests.post("https://ajontectool.com/v1/tools/pdf-merge",
    headers={"Authorization": "Bearer ajt_YOUR_KEY"},
    files=[("files", open("a.pdf", "rb")), ("files", open("b.pdf", "rb"))])

Errors and limits

Errors return JSON {"error": {"code": "...", "message": "..."}} with HTTP status 400 (bad input), 401 (key), 402 (no active plan), 403 (not in plan), 404 (unknown tool), 413 (file too large), 429 (quota or per-minute limit, see Retry-After). Every successful request uses 1 credit (AI tools use 5); requests that fail are not counted. Quotas reset on the 1st of each month. Browser-only tools (calculators, formatters) are not part of the API.
